So my friend gave me his old car that he blew up, I'm going to do an engine swap on it, but I have no idea what kind of engine I can put in it. Obviously I could just put the V6 3.4 l in it, but the LKQ that I have near me doesn't have one, and I'm kind of new to this, so can anybody help me out? 2004 Pontiac Grand am

Easiest and least expensive will be to put the same thing in that it already had.
